WRENCH.

SPECIFICATION forming part of Letters Patent No. 595,586, dated December 14, 1897.

Application filed May 4,1897. Serial No. 635,046. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM F. SELLERS,

of Gallitzin,'in the county of Oambria and- State of Pennsylvania, have invented certain new and useful Improvements in Wrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to wrenches, and has for its object to provide a wrench which can be readily adjusted to fit nuts or bursof different sizes, and with this object in view it consists of the parts and combination of parts, as will be more readily understood from the accompanying specification and claims and the drawings hereto annexed.

In the drawings, Figure 1 is a perspective view of my invention. Fig. 2 is a longitudinal sectional view through the spring-pressed.

catch of the adjustable jaw, and Fig. 3 is a detailed perspective view of the spring-pressed catch.

The shank 1 is provided on one end with a stationary jaw 2 and at the other end with a handle 3 of ordinary construction, while on the inner face of said shank is a series of teeth 4:.

5 is an adjustable sliding jaw, preferably rectangular in cross-section, on one side of which are two slots 6, through which the ends 7 of the U-shaped block 8 are adapted to fit. It will be noticed that this block is secured to the sliding jaw at 9 by means of a suitable bolt 10, passing through the perforation 11 of said block. A short way from the bottom of this block in the perforation is an annular shoulder 12, on which the spring 13, which encircles the bolt 10, is adapted to be seated. The end of the bolt 10 is secured in a crossdivision consisting of the material of which the sliding jaw is. formed and located between the slots therein which movably receive the U-shaped block 8. By this means the movable parts are held in connection with the said sliding jaw, and the spring is retained in proper position by the head of the bolt.

14 are lugs or projections upon the sides of said U-shaped block, the ends of which are preferably corrugated to enable the operator to easily release the same from engagement with the teeth on the shank 1 of the wrench.

When it is desired to adjust the jaw to different widths, the'operator clasps the corrugated portion of the U-shaped block, and by withdrawing the same out of engagement with the teeth 4 on the shank 1 the movable jaw can be readily adjusted to suit any sized nut. As soon as said block is released the coil-spring will force the said block again into engagement with the teeth 4 and hold it securely locked in the predetermined position.

From the foregoing it will be seen that I provide a device of the character described adapted to be easily adjusted and one that will be readily appreciated by those skilled in the art to which my invention pertains.

Having thus described my invention, what I claim, and desire tosecure by Letters Patent, is

1. A nut-wrench, consisting of the usual shank and rigid jaw, the said shank being provided with ratchet-teeth, a sliding jaw mounted on the said shank, a U-shaped locking-blockmovably mounted in said sliding jaw and having oppositely-disposed gripping lugs or projections provided with corrugations and formed with a central aperture havin g an annular shoulder therein, a bolt passing through the said central aperture of the U shaped block, and a coiled spring surrounding said bolt and bearing upon said annular shoulder, substantially as described.

2. A nut-wrench, consisting of a rigid jaw having a shank extendingtherefrom provided with ratchet-teeth, a sliding jaw mounted on the said shank, a spring-pressed locking-block movably mounted in said sliding jaw and adapted to engage the ratchet-teeth on the shank, said locking-block being provided with a central perforation having an annular shoulder at the inner portion thereof, a bolt passing through the said central perforation, and a coiled spring surrounding said bolt and adapted to bear upon the said annular shoulder, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
